Master Thesis: Mapping of Nuclear Spins in Diamond for Quantum Technologies

The Fraunhofer-Gesellschaft (www.fraunhofer.com) currently operates 76 institutes and research units throughout Germany and is a leading applied research organization. Around 32 000 employees work with an annual research budget of 3.4 billion euros.

At the Fraunhofer Institute for Applied Solid State Physics IAF we know our technologies like the back of our hand. Because we are one of the few scientific institutions worldwide to conduct research along the entire semiconductor value chain and on tailor-made synthetic diamonds. Whether high-frequency circuits for communications technology, voltage converter modules for electromobility, laser systems for measurement processes, or innovative hardware and software for quantum computers and quantum sensors: we develop tomorrow’s technology in-house for a sustainable and secure society. When will you join us?

In the field of quantum technology, the institute is working on the realization of a quantum computer based on color centers in diamond. Here, nitrogen-vacancy (NV) centers in diamond are used to generate qubits. Using microwave CVD, NV centers are generated by nitrogen doping during diamond growth and characterized on site at the institute with the existing measurement setups with regard to their spin properties.

What you will do

As part of this work, experiments are being conducted to detect nuclear spins of the carbon isotope C13 in the vicinity of NV centers in diamond. The aim is to detect and localize the nuclear spins using NMR sequences and to determine the coupling to the NV center. For this purpose, pulse sequences known from the literature are transferred to the experiment, photoluminescence measurements are performed on a confocal microscope, and the measurement data is validated using simulation models after further development.

Your tasks include:

Operation of a measurement setup for localizing nuclear spins in the vicinity of NV centers in diamond
Conducting photoluminescence experiments on a confocal microscope
Implementation of pulse protocols for performing NMR spectroscopy in diamond
Evaluation of measurement results and development of a simulation model to incorporate 13C nuclear spins
